This took quit some time to make, the trailer.
Very well done!! very well recorded, and, edited!
(And the font, i quit liked it Henley. But that is just a matter of taste, what is liked by one is "hated" by another one).

About the mod itself i can't say much, i am no fan at all of Portal, so each Portal mod is no fun to me, (love HL2 and the eps though), am just no puzzle fan.
